Specifically, the prior art does not appear to address the issues of overspray, leakage, drips and related problems that occur with the use of wall mounted urinals where a male is standing during the act of urination. The present invention fulfills these needs and provides solutions and further related advantages as described in the following summary.

SUMMARY OF THE INVENTION

The present invention teaches certain benefits in construction and use which give rise to the objectives described below. The invention is directed to the well-known problem of urine containment in the use of urinals. Two specific issues arise. First, it is well known that when a urine stream is directed into a urinal, impact with one of the urinal's interior surfaces creates splashes, and these splashes are often not fully contained within the urinal, but may come into contact with the user's clothing or fall to the floor in front of the urinal. Second, the floor in front of a urinal is often found to be wet with urine spillage. Such wetness is not only caused by inadvertent splashing but is primarily caused by dripping. When a man urinates into a urinal the initiation and cessation of the urination stream includes poorly directed stream control and dripping. Older men especially often have a considerable problem with stream control and cessation dripping. This not only creates an odor problem in public toilet facilities, but also a slip-and-fall liability problem to the establishment, and an embarrassment to the person whose clothing becomes wet. The primary reason why commercial urinals do not function more efficiently is that the frontal opening into which the urine stream is directed is too large and the rearwardly directed surface which receives the urine stream is not oriented for deflecting the urine stream downward. The present invention corrects this condition.

A wall mounted urinal has a detachable urinal insert where the insert provides a frontally directed opening for receiving a urine stream. The insert provides a lower surface in contact with the bottom surface of the urinal for supporting the insert, and an upper surface or a rear surface, or both, for stabilizing the insert within the urinal. A splash capturing surface defines an aperture for admitting a urine stream, the aperture comprising an area inferior to that of the frontally directed opening of the urinal and extending outwardly from it.

A primary objective of the present invention is to provide an apparatus and method of use of such apparatus that yields advantages not taught by the prior art.

Another objective is to provide such an invention capable of containing all of the urine ejected by a urinal user.

A further objective is to provide such an invention capable of containing misdirected urine especially during cessation of urination.

A still further objective is to provide such an invention capable of being inserted and engaged within a standard urinal and of being flushed by the urinal's flushing system, and of being drained using the urinal's drainage system.

Other features and advantages of the present invention will become apparent from the following more detailed description, taken in conjunction with the accompanying drawings, which illustrate, by way of example, the principles of the invention.

DETAILED DESCRIPTION OF THE INVENTION

The above described drawing figures illustrate the invention in several of its preferred embodiments, which is further defined in detail in the following description. Those having ordinary skill in the art may be able to make alterations and modifications in the present invention without departing from its spirit and scope. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of example and that they should not be taken as limiting the meaning of the present invention in any way.

The present invention, in one embodiment, is a splash and drip guard apparatus or insert 10 designed for detachable insertion into a wall mounted urinal 20, wherein the urinal 20 has a top 21, bottom 22, left 23 and right side 24, and rearwardly directed 25 interior surfaces. Most standard urinals have such construction and this is well known, but FIG. 1 illustrates such a typical urinal 20. The urinal's surfaces 21-24 define a frontally directed opening 26 for accepting a urine stream (not shown) entering the urinal through the frontally directed opening 26. The splash and drip guard apparatus (the insert 10), includes a splash capturing surface 11 extending in part, frontally and exteriorly to the frontally directed opening 26 of the urinal 20, and a lower surface 12 in contact with the bottom surface 22 of the urinal 20 for resting the insert 10 on the urinal 20. It also provides either an upper surface 13 or a rear surface 14 for stabilizing the insert 10 within the urinal 20. The splash capturing surface 11, an interior surface within the insert 10, defines an aperture 15 which is large enough for admitting the urine stream into the insert 10. The aperture 15 comprises an area that is inferior, or smaller, than that of the frontally directed opening 26 of the urinal 20 and therefore is able to prevent backsplash from the interior of the insert 10 in the embodiments shown FIGS. 3, 4, 9, 12 and 15; and also backsplash from the urinal's rearwardly directed wall surface shown in the embodiment of FIG. 6, where the insert 10 does not provide a rear wall surface.

As shown in FIG. 3, in one embodiment, the upper surface 13 preferably is part of an insert lip 16 which is in contact with a urinal lip 27 in a manner for securing the insert 10 within the urinal 20, i.e., the urinal is not able to rotate toward and through the frontally directed opening 26.

As shown in FIG. 4, preferably, in another embodiment, the exterior wall of the splash capturing surface 11 and the exterior rear surface 14 of the insert 10 are in contact with the rearwardly directed surface 24 and a lower frontal lip 27 of the urinal 20 for securing the insert 10 within the urinal 20.

As shown in FIG. 12, preferably, the-insert provides a frontal edge 16 configured for contact with the lower frontal lip 27 of the urinal 20 on two orthogonal surfaces thereof, whereby the insert 10 is prevented from moving downwardly within the urinal 20, from its preferred position, and also from moving outwardly from the urinal 20.

As shown in FIGS. 10-12 it is shown that a pair of wedges 30 may be placed between the left and right side surfaces 23, 24 of the urinal 20 and the insert 10 to jamb it in position. Such wedges 30 may also be adhesively engaged with both the urinal 20 and the insert 10.

As shown in FIGS. 7 and 8, the insert 10 may be fastened to the urinal 20 using mechanical fasteners such as screws and nuts. Such mechanical fastening may take any form and encompasses the many ways mechanics of this art might hold the insert 10 in place.

As shown in FIG. 9, the interior rear wall 28 of the insert 10 is preferably concave and presents a surface that deflects the urine stream downwardly. See arrow 40.

Clearly, as shown in FIG. 13, the aperture of the insert may provide an irregular edge such as the floral appearance shown. This floral design or similar may be more inviting to the urinal user since the insert 10 suggests that the user move closer to the unit and this is somewhat undesirable to some urinal users who are germ phobic. As a matter of fact, the spillage and splashing of urine at urinals is related to how close users are willing to stand. Such floras or other more appealing insert designs may partially overcome such hesitations.

As shown in FIGS. 13-15, the insert 10 may provide rear slots 16 and protruding portions 17 which, by laying in contact with the rearwardly positioned wall surface 25 of the urinal 20, is able to divert flush water which enters the urinal 20 through pipe 50, into the insert 10. As shown in FIG. 15, the flush water then exits insert 10 through drain pipe 60 and bottom surface 12.

As shown in FIG. 15, the may further comprise a closed compartment 70 fitted with an inlet 72 for filling the closed compartment with a weighting substance, preferably water, for securing the insert 10 within the urinal 20 by its weight.

Clearly, the present invention may be considered as the combination of the insert 10 and the urinal 20 along with the several versions or embodiments. This combination is reflected in the appended claims as well as the insert 10 alone for engagement with the urinal.
